Chapter 1: Getting started with kivy

Screen Manager

In the following example there are 2 Screens: SettingsScreen and MenuScreen

Using the first button, on the current screen will change your screen to the other screen.

Here is the code:

from kivy.app import App 

from kivy.lang import Builder 

from kivy.uix.screenmanager import ScreenManager, Screen 

 

# Create both screens. Please note the root.manager.current: this is how 

# you can control the ScreenManager from kv. Each screen has by default a 

# property manager that gives you the instance of the ScreenManager used. 

Builder.load_string(""" 

: 

    BoxLayout: 

        Button: 

            text: 'First Button on Menu' 

            on_press: root.manager.current = 'settings' 

        Button: 

            text: 'Second Button on Menu' 

 

: 

    BoxLayout: 

        Button: 

            text: 'First Button on Settings' 

            on_press: root.manager.current = 'menu' 

        Button: 

            text: 'Second Button on Settings' 

 

""") 

 

# Declare both screens 

class MenuScreen(Screen): 

    pass 

 

class SettingsScreen(Screen): 

    pass 

 

# Create the screen manager 

sm = ScreenManager() 

sm.add_widget(MenuScreen(name='menu')) 

sm.add_widget(SettingsScreen(name='settings'))
